The city of Gresham has reaffirmed the safety of its drinking water despite a regional chlorine shortage stemming from an electrical failure at a manufacturing plant.

Chlorine is used to disinfect drinking water and treat wastewater. In Gresham, the city said the water supplier should have enough chlorine to meet demand through the projected down time of the chlorine plant.

That means Gresham's tap water remains clean and safe to drink, with no need to stockpile water, city officials said.
